I forgot to add that 2400 to 2450 is being taken away more and more, we for exsample are only allowed to use it for satalite communication making using modified wifigear for that band useless for us. Op 06-07-13 13:00, PE1RDW schreef:
Lucky hamradio and amrp is not limited to the USA so most of us do not have to worry about the USA limitations.
In region 1 we got between 6 and 10 Mhz and usualy only 1 Mhz is in active use leaving plenty of room for high speed data modes especialy if FHSS is used.

(6) A RTTY, data or multiplexed emission using a specified digital code listed in §97.309(a) of this part may be transmitted. The symbol rate must not exceed 56 kilobauds. A RTTY, data or multiplexed emission using an unspecified digital code under the limitations listed in §97.309(b) of this part also may be transmitted. The authorized bandwidth is 100 kHz.

(Please trim inclusions from previous messages) _______________________________________________ First of all it uses FHSS so it is not so interfeer to the other users ... second the bandwith can be adjusted (on the throughput of course) up to 2 MHZ if i remember correct but for me the big benefit is that it allow to have a mobile connection because it does not require line of sight a thing that 2.4GHZ require and also with 0.5W on 70CM you can get much bigger distance then with a regular WIFI gear
